THE HAL - CLOVER-2000 DSP4100 2K
The DSP4100 2K is an HF data modem that provides CLOVER-2000, a 2000 bits/sec., voice bandwidth, adaptive
waveform specifically designed for HF radio data communications. CLOVER-2000 measures real-time HF signal
conditions and sets the most efficient modulation for these conditions. 8-bit data is sent without extra
manipulation or modification. ARQ mode is simultaneously bi-directional duplex and does not require an OVER
command. FSK waveforms CCIR 476/625 TOR, P-MODE, Baudot and ASCII are included. Housed in an RF tight
shielded enclosure, the DSP modem operates on 10 to 18 volts DC. Internal modem software can be uploaded
into the DSP 4100 2K into non volatile flash memory, greatly simplifying addition upgrades. The DSP4100 2K
is particulary well suited for use with lap-top terminals PC's in a portable and/or field enviroment. Many
third party software packages are available. | |
